We have been toying with a new oven for a while
Just wondering how many Watts others see on the smart meter when their oven is on

Ours pulls about 1.5 kw is that good / bad or in different ?

I'd have said indifferent.

Assuming ovens are about the same size then all things being equal will use the same amount of energy to heat the oven to the required temperature. Some may use 2000W for a shorter amount of time than one that uses 1500W, but the net result will be the same energy consumption.

Likely the only thing that can make a difference is the quality of the insulation of the oven. Better insulation resulting in less energy leaked into the room. That said, the savings are insignificant as opening the door once during a 30 minute "bake" will negate any savings any amount of insulation could have made anyway.

Ah but for the PVers on these boards, the power an appliance draws can actually be more important than the total energy consumption.

Ours is Neff, as was the old one. Pulls about 2,300W on fan oven. Some of the other options pull less. The rating should be on the oven somewhere. I think you can pretty much say it will pull the rated watts when either the fan element is on or the traditional oven elements are on.

We now have a Neff warming draw which only pulls 1,200W. You actually slow-cook in it but not yet tried that.

Also, new Neff microwave has grill function and pulls about 1,600W. Again, once we get our heads round it we might find we use that rather than the traditional oven for some cooking. Jacket potatoes are quite good in it. Not as quick as just microwaving and not quite so crispy skins as in the oven but not a bad compromise and PV-friendly...

Good point and having just nuked my jacket potato in the combi-oven without touching grid electricity, one I should have thought of and can definitely relate to :beer:
